This invention is particularly concerned with the preventing of trash ofall kinds from falling on the drop wires or detectors forming part of awarp stop motion equipment of a loom. As is well-known in the art whenlint or other trash on the warp is permitted to come into contact withthe drop wires or detectors draw-backs, breakouts and otherobjectionable defects de- 6 Claims. (Cl. 139349) through the medium ofhinges tending walls 9, l0, respectively, hinged as at H and P2 to astationary wall section l3 that extends Briefly, the present inventionconsists in the provision of a combined drop wire or detector fingercover and warp brush for attachment to the loom to substantially enclosethe drop wires and to wipe the warp clean to thereby preclude thepossibility of lint and other trash on the warp passing therewith intocontact with the drop wires or detector fingers.

The invention together with its objects and ad-' vantages will be bestunderstood when the following detailed description is read withreference to the accompanying drawing in which is illustrated what ispresently considered a preferred embodiment of the invention, andwherein:-

Figure 1 is a fragmentary perspective view of a loom illustrating apractical application of this invention;

Figure 2 is a perspective view of the combined drop wire cover and warpbrush emboding the features of this invention;

Figure 3 is a front elevational view of the combined drop wire cover andwarp brush, with a frame part of a loom shown in cross section, andillustrating the manner in which the device of this invention is mountedon the loom and the movability of parts of the device with respect tothe loom; and

Figure 4 is an end elevational view of the drop wire cover and warpbrush with the longitudinal wall sections thereof shown in a partiallyraised position.

Referring now in detail to the drawing it will be seen that thecombination drop wire cover and warp brush of this invention is in theform of an attachment to be applied to a loom without altering thestructural details of the latter. To that end the device comprises apair of attaching plates 5-5, a hood having end walls 6 that aredetachably connected to the members between the end walls 6 and issecured at its opposite ends to the walls 6 at the upper edges of thelatter as at M.

The aforementioned hood comprising the walls 6, 9, Ill and I3 may be ofany suitable cross sectional shape, the only requirement as to the crosssectional shape and longitudinal, dimensions of the hood being that theybe sufficient for the.

hood to extend over and substantially enclose the drop wires l5 of theloom it (see Figure 1) to which the hood is applied as contemplated bythis invention.

The wall 9 of the hood is provided at its free longitudinal edge with aflange I! to which is.

While the brush secured as at I8 a brush 19. may be of any suitableconstruction, it preferably embodies a back or base portion formed froma or trash that might fall on the warp.

It is also within the contemplation of this in- I vention to provide thewall ID at its free longi- It may be also here stated that when desireda suitable} brush may be suspended in any well-known mantudinal edgewith a rolled edge 20.

ner from the edge 20 of wall It for brushing loose ends of the threadsfrom the warp so that the loose ends will be free to fall to the floorfree of the loom.

There are also suitably mounted on the wall section [3 of the hood ringsor eyelets 2! which may be selectively engaged with any suitablesuspension means (not shown) mounted on the loom l6 above the drop wires[5 for holding the hood in, for example, the partially raised positionshown in Figure 3 to permit access to the drop wires [5, as might onoccasion be required.

In applying the device of this invention to the loom l6, and as shown toadvantage in Figures 1 and 3, the attaching plates 5 are secured toopposite portions of the frame IEO. of the loom l6 at the desiredposition of vertical adjustment through the medium of tap bolts 22 thatare threaded into the frame Ito and extend through slots 23 provided inthe attaching plates 5. The plates 5 thus serve to support the hood ofthe del equipped with removable hinge pins 8, and longitudinally exvicetransversely on the loom and over the drop wires l which form, as iswell-known in the art, part of a thread detecting mechanism or electricwarp stop motion now generally constituting standard loom equipment, andthe brush IS in wiping engagement with the warp 24.

In actual practice with the hood and brush of this invention in properposition on the loom and as shown in Figure 1, the hood will effectivelyserve to substantially enclose the drop wires !5 to prevent lint,cotton, and other trash from falling on the drop wires, while at thesame time the brush, being in wiping engagement with the warp 24, willserve to effectively pick up all loose ends of the warp and cotton andtrash that would otherwise fall on the warp and, in the absence of thisinvention, be carried with the warp into the drop wires, or as they aresometimes referred to in the art, detectors l5.

It is well-known in the textile industry that lint, cotton and othertrash which is permitted to contactthe drop wires or detector fingers 15of a loom cause what are known in the art as mat-ups,v

draw-backs, breakouts and other defects in the finished cloth With myinvention the causes of these defects in the cloth are prevented byreason of the fact that through the medium of the hood and brushassembly contemplated by this inventionand' operating in the mannerherein described trash of all kinds is precluded from fallin on the dropfingers or detectors [5 of the cm. As a result a loom'equipped'withadrop wire cover and a. warp brush assembly as herein described willproduce a high quality of cloth and at minimum cost,,tl1eproductioncapacity of the loom. being materially enhanced as will be apparent tothose skilled in this art.

It will also be appreciated from the detailed description oi thisinvention that either of the walls 9 and "I may be swung upwardly on thehinges" H and l2'soas to permit ready access to the drop wires !5 fromeither side of the hood; and thatalso' by removing the hinge pin 8 of aselected hinge T the hood may be vertically swung upwardly on theother'hinge i as suggested in Figure 3 seas to expose the entireassembly of drop Wires l5 and thereby permit complete access tc-thewires:

Also by vertically adjusting the plates 5 on the. frame Him the hood andassociated brush ['9 are supported at the desired position of elevatedad.- J'ustment with respect to the drop wires and warp 24 as desired andas conditions of use may dictate.

While the invention has been described in detail in its presentlypreferred embodiment, it will, of course, be understood that such hasbeen done for purposes of illustration only and not by way oflimitation, and therefore only such limitations are to be imposedthereon as may reasonably come within the scope of the appended claims.

What I claim is:

1.. A combination dropwire cover and warp brush for looms, comprising acasing adapted to be mounted on the loom to substantially enclose thedrop wires, and a brush disposed on the casing for wiping. engagementwith the warp.

2. A loom attachment comprising a casing for disposition over the dropwires of the loom, and a brush mounted on the casing and extendinglengthwise thereof for brushing contact with the warp andzco-acting withthe casing to prevent lint and other trash from falling on the dropwires 3..A loom comprising. in combination, drop wires,.

a casing substantially enclosing said. drop wires,

and a brush mounted on the said casin in brushing. contact. with thewarp.

4. A loom comprising in combination, drop wires, a casing disposed oversaid drop wires,v

a brush mounted on the casing in wiping contact with the warp, andinterengaging means on the loomand on the casing for supporting thelatter andbrush atv selected positions of vertical adiustmerit ontheloom.

5. A casing. for disposition over the drop wires of a loom comprisingattaching members, a hood.

having end. walls hinged to the attaching members, and longitudinalwall. sections hingedly supported between the end walls.

6..A.casing for disposition over the drop. wires of. a loom comprisingattaching members, a hood having end walls hinged to the attaching.members,.and longitudinal wall sections hingedly supported between theend walls, and a brush.
